A band of heavy precipitation will pivot across eastern portions of North Carolina, Virgina, and the Delmarva Peninsula before exiting off the coast. A cold front pushing southward through the Plains today combined with shortwave energy moving through the four corners region will create a wintry scenario for the Central and Southern Rockies stretching into the Central Plains. Easterly upslope flow will enhance precipitation across the higher elevations of Colorado and Northern New Mexico. Heavy snow is expected later tonight and into tomorrow morning before lighter snow spreads into the Central Plains tomorrow afternoon. Quite weather is expected across the Pacific Northwest over the next 24 hours before deep Pacific moisture overtakes the region for the remainder of the weekend. A ridge currently in place over the west will be broken down by a series of shortwaves moving through the region. The first piece of energy will crash into Southern British Columbia by tomorrow morning. A fresh supply of deep Pacific moisture will be drawn northward ahead of a cold front approaching the west coast. Heavy rainfall is expected to begin impacting western Washington between 12 and 18z tomorrow and continue progressing southward through the day as a cold front pushes through the region. By Saturday morning the front will be pushing through central Washington and heavy rain/high elevation snow will spread to the Northern Rockies.
